Hearts of Iron 2 Complete

Paradox Interactive has released a seven minute documentary video that goes over their development history, starting with Europa Universalis. From there, the team reveals how each game is connected, and how they try to improve upon their predecessors.
Of course, the video serves not only as a look back, but as a look forward as well. Runemaster is the company's upcoming RPG--a first for the studio. The video shows some new footage of the game in action, a procedurally-generated adventure that spans the six worlds of Norse myth.
